The object; of my invention. is to provid'o a coke oven in which there shall be equai'. distribution of the gas throughout. tho length; of the oven all the time; an equal distribu-g tion of air to all the gas fines that, are in; operation during a heating poriod; and an. equal distribution of the stack draft; to all the ports extracting the products 05 corn bn-stion from the fines that, are in action; in which the air for combustion wiii he deiiv; cred at the highest possibio teinp zrntnru at; the point of mixture with the gas to brburned; in which wide variations of the; temperature of the Wail resulting in. oxcossive contraction and expansion wiii be avoided; in which wind will be "Without effect on the circulation of the gases and. which will have greater strength. of wail structure than ovens of which I. have any linowiecige and for the attainmentof this object and others my invention consists in the coke oven hav ing the construction substmitiaiiy as herein after specified and claimed.

The gas Iiues are preferably divided by a wall 150 so that there may wcrai groups of burners, each group oon'ununioation with a particular 890- r sub-division of the gas flue. sniuoh as I dispense with the neo *ssity ng a horizontal flue, the oven wall is nosed in strength over a construction einpioying; a horizontal flue, and with my conion the unprotected surfaces of the ivaii are reduced to a minimum.

by my invention a uniform heat from end to end of the oven is secured, the requisites to secure uniform heat being found in my oven and consisting in'uniforrn gas distribution, uniform air distribution, uniform stack draft distribution, and uniform frictional resistance to the passage of air, gas and products of combustion in the combustion lines. 1 secure uniformity of stack draft by the provision of two separate points ailorded by the two pairs of primal regenerators where the staok arm acts, and the location or such points with reference to the combus- 1 lines to reduce to a minimum the disto he traveled to the staokror outlet.

greater the distance to traveled, ohi 'y the greater the variation of the stack draft on the lines and the greater the likelicross currents. As the air, gas and is of coinbusiion in all the COIDlDllS es have the same distance to travel in iiuoa, and as tho form of the combustion il l the lion fives eliminates the existence of cross with said individual regenerzitors.
